MACHINE FOR MAKING ICE-CREAM CONES.

Application filed September 30, 1920. Serial No. 413,772.

To all whom it may concern:

Be it known that I, JOHN Muck, a citizen of the United States, residingat Milwaukee, county of Milwaukee, and State of llViscon- 5 sin, haveinvented'new and useful Improve- 'ments in Machines forMaking Ice-CreamA Cones, of which the following is a specification.

My invention relates t0 improvements in machines for making ice creamcones and `similar articles of pastry, l

.The primary object of my invention isto provide means for making pastrycones with minimum waste of material. Further Vimportant objects are toprovide improved means for delivering the cones from the machine inwhich manual attention and labor are reduced to` a minimum, and dangerof injury to the operator avoided; in which the cones or 4other articlesare released with the `greatest possible freedom and in such'a Inanneras to avoid weakening or tearing the material; in which the plunger dieis accurately positioned while being inserted in theV .matrix, therebyproducing cones or devices having walls of substantially.uniform thick`ness; to provide for a downward withdrawal of the finished product fromthe matrix, followed by a downward withd `awal of the product from theplunger die, whereby `delivery of the product is assisted by gravity andwhereby the product may be exposedin a position most convenient for suchfurther operations as may be necessary to remove the material from theplunger; and in general to produce a more efficient vand reliable meansfor producing pastry cones and similar articles than those heretoforeused for such purposes.

An embodiment of my invention is shown in the drawings in which,

Figure 1 is a side elevation of a machine vembodying my invention. j

Figure 9. is an enlarged. detail view of the front end portion of thematrix carrier partly in elevation and partly in section.

Figure 3 is a detailfview partlyin front elevation and partly insection, of a plunger Y and die in 'cone forming relation.

Figure 4 is a front elevation of the slide carrying head, with one ofthemale dies or plungers in position.

Figure 5 is a cross sectional View of the .shaft 4.4i and the front arm42 drawn to a plane exposing the pivotal connection of rod 70.

Figure G is a plan view of a matriXcarrier.

Like parts are identified by the same reference characters thruout theseveral views. An endless chain of matrix carriers is arranged to travelbetween pairs of` end sprocket wheels 2 and 3 supported by shafts 4 and5 respectively. Each matrix carrier has two laterally projecting studs 6on each side, provided with sleeve rollers 7 adapted to travel alongguide rails 9 conforming generally to the path followed by theendlesschain of matrix carriers in traveling about the sprocket wheels,but supporting the matrix carriers to travel along a substantiallystraight line between the sprocket wheels.

Each matrix carrier is provided with one Vmatrix cavity 12, and isformed with a movable section 13 pivoted to the body of the carrier at14;. The inner surface 15 of the movable section constitutes one half orsubstantially one half of the wall of the matrix cavity; the opposingwall of the cavity being" preferably integral with the'body or majorportion of the carrier. The movable section 13 is adapted to swingoutwardly on its pivotal connection 14 to release the cone after it hasbeen formed and baked as hereafter described.

That portion of each matrix carrier which projects outwardly from thepitch line of the sprocket wheel when traveling about such wheel hasflat surfaces 16 and 18 respectively, adapted for abutting contact withthe corresponding surfaces of adjacent carriers. The outer surface ofthe movable section 13 is prefer bly somewhat inset from the plane ofthe surface 18, but has an outwardly projecting rib 27 along its uppermargin, the surface of which lies in said plane when the movable sectionis in normal position. Therefore it will be obvious that when the chaintravels along a straight line with the fla-t surfaces 16 and 18 ofadjacent carriers in contact with each other, section 13 will be swunginwardly to its normal position with its inner surface 15 marginallycoinciding with the corresponding surface of the body portion of thecarrier toform a matrix 'cavity having a continuous7 wall taperinginwardly and ot' the proper size and contour to serve as a mold for thepastry cone to be formed therein.

But when the carriers travel around the sprocket wheel 3 in thedirection indicated by the arrow in Figure 1 the movable sec tion 13will tend to drop away from its normal position by gravity inasmuch asthe flat surfaces 16 and 18 become separated when the carriers travelalong'a curved line, i'. e., when they follow the pitch circle of thesprocket wheel 3. But when they chain of carriers is revolved in thedirection indicated by the arrow in Figure 1 the movable section oi eachcarrier will be on the upper side in traveling about sprocket wheel 2,and, will therefore remain in its normal position.

Gin the upper side of the chain of carriers I provide a feed' pipe 24having suitable apertures or nozzles at thru which the batter may dropas indicated at26 in Figure vthe matrix whilethe latter 1. rlfheapertures 25 arey of such size as to deliver the required quantity etbatter to is passing underneath it. H v

The delivery however, will preferably be intermittent, any suitablemeans (not sho-wn) and the wall of the matrix and thereby form a conicallayer between the plunger andthe matrix wall. Y y

Each plunger is provided with the head piece 30 havinglaterallyprojecting studs 31 provided'with sleeve rollers 32 which travel 'theescaping gas may be ignited.

along a trackway 33 adapted to hold vthe plunger in the matrix while thematerial is beingbaked, both the plunger and thematrix being'heated orkept at the proper bak.-

ing Vtemperatiire from `the point at which the plunger is inserted inthe matrix to a point of delivery at 3l. Any suitable heating meansmaybe employed, such for exam.- pleas thev gasburner 35 comprising a curvedpipe having suitable jet apertures at which Horizontally disposed gasburners 36 may also be employed in the space between the sprocket wheels2a1rd 3, and particularly in the rear portion of said space, whereby thematrix carriers and plungers may be heated both from above Vand belowand a. maximum degree of heat applied during the initial portion ot thebaking operation, to promptly raise the temperature of the matrixcarriers and plungers to the desired degree.

T ackway 33 is duplicated on each side ot the path traveled by theplunger heads 3U,

and these trackways are provided with a spaced rel-ation. tothe walls otthe matrix cavity on all sides.

To insert the plungers in the matrices a slide Ll() is preterablyemployed, the tra-me members 41 having the trackways 33l on their innersurfaces, are formed with upwardly extending arms .l2 which are con-Atoured to serve as guidesforf the slide This slide is provided on itsv'front surface with a transverse pivot shalt del, having near each enda depending arm 4:5 which is ian shaped in contour and provided near itslower .end with inwardly projecting rollers 116 upon whichI the, ends ofthe plunger supporting rollers 32 may be received and supported. Vfr setof curved springs ll' `are adapted to bear upon the'upper surfaces otthe sleevev rollers 32 when so supported, the outer end of each springbeing upwardly curved to. allow the plunger heads to be moved intoposition with the sleeve rollers 32 upon the rollers 46. The pivot shaft417 with its depending arms 15 and rollers l therefore constitute aplunger carrier connected with the Y'slide 40 and movably with it.llVhen the slide is moved downwardly 4the' engaged plunger will besupported in a posi-tion to enter one ot the matrices disposed beneathit and until the final downward movement of the slide and springconnected with the frame will push the plunger carrier o'rewardly towithdraw the rollers 46 t'rom beneath the sleeve rollers 32, therebyreleasing the plunger. This movement .will occur after the dowel pins 39have. entered the sockets in the matrix, which registers with them.

mmediately alterl the insertion of the plunger the matrix carrier isadvanced sutticiently to carry the rollers 32 past the rounded corner 52at the upper front ends ot the trackways 33. rlhese trackw'aysthereafter hold the plunger in `position until it has traveled aroundthe sprocket wheel 2 and forewardly on the under side to a point whereit commences to travel a circular path around the sprocket wheelY 3.Thereupon the matrix carriers will separate from each other youtside ofthe pitch circle' et the sprocket wheel and the movable section 13 willdrop away or swing pivotally in a downward direction. This will allowthe plunger to drop out of the matrix by gravity and owing to theseparation of the matrix walls or wall sections the pastry conewilladhere most strongly to the plunger and will drop with it out of thematrix.

lll/hen the plunger drops out of the matrix as above described itssleeve rollers 32 will engage inclined Aguides 56 carried by the machineframe wherebythe plunger will move downwardly until the rollers 32 arereceived and their motion arrested by hooks 57. The plunger will occupya position between these guides 56 and subsequently be tween the hooks57, and will swing by gravity to a substantially vertical positionVwhereupon when the downward motion of the plunger' is arrested thepastry cone will tend to slip 'from the plunger and drop into a.lreceiver 58 as indicated by dotted lines at 59.V

'After delivery of the pastry cone from the plunger the latter may beremoved from the hooks 57 by a set ol' levers GO.' These yhave upwardlyprojecting arms (il suitably7 socketed at their upper extremities asshbwn at GS'and adapted to engage the rollers 32 in these Vsockets nearthe respective ends ot said'rollers. vThe continued upward move` ment ofthe levers 60 will then lilt the plunger from .the hooks 57 and deliverit to the plunger carrier connected with the slide 40, said carrierhaving in the meantime been elevated by the slide to the dotted lineposition in which it is illustrated in Figure 1.

The chain oimatrix carriers may be actuated either continuously or stepby step from any suitable source of power. The mechanism for so doing isnot deemed `important, such mechanisms being common and known to allmechanics. Detailed illustration and description is therefore not deemednecessary, but for the purpose ol this specilication it may be assumedthatl shaft 5 is driven by one of the levers 6i) which has a stud 6ladapted to engage a lever 62 during the final portion of the upwardmovement of lever 60. The lever G2 carries a spring actuated pawl 63positioned to actuate a ratchet wheel Get lixed to the shaft 5. Theparts are so proportioned that each advance of the ratchet wheel willadvance the carrier a distance equal to the distance between centers oftwo successive motion of the lever GO, the slides Ll0 and the matrixcarrier may be synchronized.

lt will be understood that a sutiicient number of plungers will beemployed to provide one plunger for each matrix in the series as it isbrought into position underneath the plunger carrier operated by theslide 410, that is to say, the number oi plungers will be equal to thenumber oli matrices in the series between the point of plunger receptionand the point il at which the plungcrs are delivered, including thematrices located at these points as well as those between said pointsalong the line ol tra y'el defined by the tracliwi 232 and ll.

It is obvious that any desired number oi carrier chains may he mountedupon the shafts l and 5 by simply extending the length ot said shattsand multiplying the sprocket wheels, tracltways and associated slidesand plunger liiting levers. lt is also possible to multiply the number oplungers connected with a single plunger head, whereby one plunger witha series oi' plunger heads may be utilized in connection with a seriesot parallel carrier chains in proximity to each other. ln such case, thelength ot' the plunger head would, ot course, be extended accordinglyand a single set; oi operating levers and slides would be sullieicnt allthe plungers. These modifications Liior will readily suggest themselveste the ordinary mechanic, and further illustration is there-tore deemedunnecessary.
